I am the reporter of FS#30444, and I've filed and patched a bug of a little project with the identical problem: If you are using iso-codes from extra repo, there is a common name of “Taiwan, Province of China” which is named “Taiwan”. And by using that, “Taiwan, Province of China” and “Venezuela, Bolivarian Republic of” are changed to “Taiwan” and “Venezuela”.
I don't hope these mirrors get removed by the way. One of the mirrors in Taiwan is Tier 1. -- Yao Wei
